What is an .iso File? An .iso file (or ISO image) is an archive file that contains an exact copy of the data from an optical disc, such as a CD, DVD, or Blu-ray. Legitimately, it is used to distribute large software, operating systems, or games—often for mounting as a virtual drive or burning to physical media. Why BLACK MYTH- WUKONG.iso is Likely Malicious Black Myth: Wukong is a commercially released action RPG developed by Game Science. The official PC version is distributed exclusively through legitimate digital platforms (Steam, Epic Games Store, WeGame). No official version of the game exists as a standalone .iso file for download from third-party websites.
